Wine From Here have posted a trailer for the movie. The documentary is about the burgeoning natural wine movement in California, which is a post-industrial process for making wine without the long list of chemicals, additives and processes used by industrial wine makers. Most natural wine makers use grapes from vineyards that are unsprayed and sometimes even unirrigated. They add no sugar or yeast, make no changes for acidity and they add either very little or no sulphite (the stuff universally overused in industrial wine that can wreck the flavor).
Natural wine is a global movement, but the documentary focuses on 14 winemakers in California.
We're really glad this documentary has been made, because anyone who drinks wine needs to understand how conventional wine is made (it won't be pretty), and also why natural wine is so much better.
Our own favorite natural wine maker, A Donkey and Goat, is featured in the documentary.
